ExcelLock helps you
to hide your Excel formulas. This
way the algoritms you used for your computations are not visible in the locked Excel
file. When a locked file is viewed in Excel through the
ExcelLock viewer the formulas cannot be recovered. The cell shows
the result and the formula editor cannot be displayed.

When ExcelLock locks
the spreadsheet it will scan the file looking for any
unsecured formulas. ExcelLock will hide these formulas
automatically when the file is locked. An analysis will be
performed on cells that can be changed as well. By
default cells are not changeable. If you want to allow
cells values to be changed you need to unlock them using
the Excel format cell function (protection tab).

If hiding formulas this way is not
secure enough for you we can offer the service to put the
formulas in a dll. The function calls in the spreadsheet can
be replaced to calls to a dll where we can implement your
algorithms. We can make an installer for you that installs the dll with the
ExcelLock viewer so the end-user has everything needed to view your file. Please contact
us if you would like to know more.
